Ford Excursion :: O-Ring Seal Was Broken - Low Pitched Hum Noise From Power Steering
Jan 3, 2016
When I was going through the engine compartment of the recently acquired 7.3 yesterday, I noticed the power steering pump cap was not on properly and only had one of the two tabs locked. I pulled it off and discovered that the o ring seal was broken.....so I went to advance and found an o ring that fit properly and replaced it. Noticed that the PS fluid was very dark and discolored. When I would start it up whenever I turned the wheel it made a weird noise, not a whine but more of a low pitched sound. Then it went away. Figured I needed to address it asap.
I had the power steering system flushed today through the pump at a local fluid change company with Mercon V before any further damage could be done and they told me the extracted fluid had water in it because some of the fluid was a light pink. As well as very dirty. I bet that the loose cap let all sorts of dirt and water in. The rest of the fluids looked good.
I have no issues with steering or brakes, but there is now a slight hum at times now that I did not notice before. Mainly at low rpms. Brakes are actually better now than they were before. The more I drive it the less it seems to hum.
Eventually am going to flush near the booster and put in a magna filter and synthetic but I couldn't leave it the way it was.Should I be concerned with the low, intermittent "hum" at times or is that just air that needs to be worked out of the system over the next few days?

I am tearing down my junkyard engine to prep it to put into my truck and I came across this on the rear main seal... is this a wear ring?
It kinda looks like a oil slinger. My new seal is on the way so I have nothing to compare it to.
I don't want to be yanking on it if it's supposed to stay.

Today I noticed I broke my steering stabilizer shock. It it broke at the connection on the piston arm where it connects to the steering linkage and the piston shaft is bent. Guess it happened when I hit a rock Thursday. I am thinking of purchasing the Rancho 9000 adjustable shock as a replacement. I do not do much off road driving and what I do is very moderate. This is for a 04 Excursion, 4x4, 6.0PSD, with 285 all terrain tires, no lift.

Looking for a write-up on replacing the seals on the hose that leaks at the power steering pump? I replace them once but may of over tightened them. I pour in atf and see it dripping on drivers side of power steering pump. Can I just use regular o rings?

For what it's worth I have been feeling a bit of a tug for 3 weeks. That's about 150 miles or 5 times driving. Installed new sway bar damper.
Pulling into the driveway the heard a ting, and look to find the inner seal of the hub spinning on the stub shaft!
An exploded view of this front end hub/bearing/brake assembly?

My car is in the shop and has a leak at the Power Steering Pump. The rubber O-ring on the Power Steering Pump Solenoid Valve (p/n 4417030120) is leaking fluid. The Solenoid Valve is ok, just the Rubber O-ring is bad, but it looks like you have to buy a complete new Solenoid Valve to get the O-ring (a lotta bucks).
I did find a Lexus Power Steering Pump rebuild kit online at, but I can't see if it includes the solenoid valve o-ring or not. Have to replace their solenoid valve o-ring?

My front carrier is leaking at the bottom of the Ring and Pinion Cover. I am going to pull the cover and replace the gasket. I am also a believer in Amsoil full synthetics, should I use the Severe Gear 75W-90, Severe Gear 75W-110 or the Severe Gear 75W-140. How many ounces does it take. I presume to fill until the bottom of the fill hole? What are the torque specifications for the bolts?

I noticed on my 03 excursion on both sides of the front axle there is a circle plastic o ring behind the u joint that is lose? Nothing is leaking and no signs of leak marks ever. Kind of looks lik a spacer ring of some sort because its at least 1/8th inch thick plastic. Also some time ago I posted about a whistling noise but never got a answer but its only there when im in 4wd there is a whistling noise from my right side and my locking hub when I turn it the hub seems lose and has a crunchy feeling to it. I just bought it a few weeks ago and now I am running into a whistling noise and noticed theres a piece of plastic that looks like a spacer....

My truck was stolen over the weekend. Fortunately, it was recovered but they broke the key lock on the steering column and I'm having a hard time getting it started. I can turn the ignition all the way to the start position with my key or a screwdriver but the starter never engages. I'm sure I'm missing something simple but I can't seem to figure it out. Looking for instructions on how to get this started again?

On my wife's 2013 Tiguan SEL, i took into a indy VW repair shop, to have the seatbelt chime disabled cos i don't have a vagcom myself.
Anyway he went to instruments, adaptation, and found it in there, which gave him four options, the factory setting was 2, he couldn't load 1, because it failed, but was able to load 3.. 4 also failed.
I think when i say 1,2,3,4 it said channels ??
Anyway, given 1 & 4 failed, only left him with 2 & 3, 2 being the factory setting.. However for 3, the seat belt chime is disabled BUT only after 6 high pitched beeps... If the seatbelt is on during startup there's no high pitched beep.. If you take the seat belt off after ignition its all fine, no beeps, actually a better way to describe it is the seat belt chime is disabled, apart from the 6 high pitched beeps, if you turn on the ignition without the belt clicked in..
Is there anyway to turn off the annoying 6 high pitched beeps...

I left the truck parked from April thru September. I can't remember if it was groaning when I parked it in April.
It sounds like the power steering pump going bad on a 1980s Chevy truck. Only it doesnt get louder when I max out the steering wheel in either direction.
It is a slight hollow/nasally groan sound. Perhaps a dirty turbo? I thought the hollow sound might be an echo in the turbo.
It does not seem to effect the performance what so ever.

I'm beginning to notice a high pitched whine when I first start up my 2008 LS600hL and turn the wheel slightly (like backing out of my garage). It almost sounds like the beginning of a power steering pump problem, but I think our power steering systems on the LS are electric.
Experiencing a slight whine/growling sound when the car is still cold and the wheel is turned? Maybe the sound has been there all along and I'm just now noticing it.
I did a search on this topic and came up empty. My car is still covered under a CPO warranty, so I'm not too concerned, but was wanting to get opinions from the forum on possible causes (or if this sound is a normal part of the electric power steering we have).

I bought my wife a 2011 GX460 from Lexus. On my way home i realized the car was in KM not MPH. The outer ring is in KM and the inner ring is in MPH. The dealer thought they were going to be able to change but turns out they can't. I'm at a crossroads, what do i do. They offered to try and find a new car or i keep the car and we work out a deal of some sort. If i keep the car will i run into other issues with it being from Canada. So, what makes a 2011 GX460 from Canada different then one from the US ?

My Santa Fe has a broken power steering pump pulley. Darn thing broke right around the spindle! I can not find a replacement anywhere. I've tried to find a one new, used and at the upull lots (only one Santa Fe in at Pick n Pull dang thing was stripped clean!). The pump is easy to find but this pulley is a ghost!

I was getting ready to replace the carrier bearing and noticed the rear pinion seal is leaking. Before attempting the replacement myself, I would like some opinions on the noise in the video below. Is this normal? I am confidant I can replace the carrier bearing and pinion seal, but not sure I have the tools for anything else.

Well, the ac in my truck has been less than exciting since I've owned it and its time to address it before another trip.
I crawled under last night to explore the Ac clutch air gap and found that the shaft seal is leaking and clutch is grooved pretty bad and covered in oil.
I'm thinking it's time for a compressor, clutch, orifice tube, expansion valve and reciever/dryer. Does that about sum it up? I haven't messed with AC systems much outside of my simple jeep system that was as easy as two seals and recharge in my garage to fix it.
Do I need to flush the lines out? Should I do that at all? Motor craft worth the cost over something like four seasons? Its almost twice the cost but in the end if something goes I'm further downstream after freon etc to charge it and the possible shop charge if I pay to have to done.

I unstuck my front axles yesterday and while under the car spinning the front axles freely and enjoying my easy fix, I noticed a rubber seal (a thick squared edge round rubber seal) sitting loose and spinning freely. Its next to the axle joint, right before it disappears into the housing.
I'm guessing this is a dust seal of some kind. There is no fluid leaking out...
I'm wondering if I can just press fit this thing back into place or do I have to take the whole front wheel assembly (hub, bearing, axle, etc) to get the seal back into place.
I'm wondering if it broke off from a larger seal or if this is the whole thing? You can see how the seal isn't sitting quite straight. It actually just spins around.
